Ballas arrived around 1 p.m. and shortly thereafter enjoyed lunch, a few cocktails and soaked in some sun before heading into LIQUID’s main pool to cool off. There, he mingled with several fans and friends before a group of gorgeous girls surprised the birthday boy with LIQUID’s infamous champagne shower and a birthday cake in the shape of the DWTS disco ball trophy.

Resident DJ IKON got the party started and JFK of MSTRKRFT set the party mood behind the DJ booth for the rest of the afternoon for the birthday boy as well as other VIP guests at LIQUID including actress Megan Good, “Pawn Stars’” Olivia Black rapper Fabolous, who performed later that night at HAZE Nightclub, as well as the NFL’s, Chris Johnson, Michael Bush, Antonio Cromarte, Denny Hamlin and Alan Ball, Jason Allen, NBA stars Rashard Lewis, John Wall, Javelle Magee and Ty Lawson.

Ballas kept the party going into the night, heading to Bellagio’s premiere nightlife destination, The Bank Nightclub. It was like a DWTS reunion at The Bank as Ballas partied with Cheryl Burke, Lacey Schwimmer, Joey Fatone and Carson Kressley. It was a true dance party at The Bank, with resident DJ Karma on the 1’s and 2’s, and these DWTS stars definitely got down, dancing the night away.
